Description

Technical Field

[0001] This utility model belongs to the field of steel bar processing technology, specifically relating to a safety range warning device for CNC steel bar bending equipment. Background Technology

[0002] A CNC rebar bending machine is a mechanical device that can set the bending angle and size of rebar through a PLC program to perform shaped processing of the rebar. This device is semi-automatic and requires manual assistance during the rebar processing. Therefore, there is a safety risk of the rebar hitting the operator. To avoid such safety risks, a safety range warning device for CNC rebar bending machines is being developed.

[0003] Chinese patent publication number CN206838990U discloses a CNC bending center for reinforcing bars, including a reinforcing bar placement rack and a bending platform. The reinforcing bar placement rack has a left-right elongated structure, and the bending platform is located in front of the placement rack. The bending platform includes a lower slide rail, on which bending clamps and clamps are mounted. The bending clamps and clamps are respectively mounted on the slide rail and each has a first motor connected to the slide rail. The bending clamps include a left bending clamp located to the left of the clamps and a right bending clamp located to the right of the clamps. The bending clamps include a base, and behind the base is a bending disc driven by a second motor. A movable bending pin is located in front of the bending disc, and a fixed bending pin is also located on the base. The first motor and the second motor are connected to a CNC control device. This device has the advantages of low labor intensity and suitability for mass production.

[0004] However, the current device has the following problems: during the bending process, the steel bar deviates and comes into contact with other parts of the device, causing it to deviate from the correct shaping and processing trajectory and strike the operator's body. Therefore, we propose a safety range warning device for steel bar CNC bending equipment. Utility Model Content

[0005] The purpose of this invention is to provide a safety range warning device for CNC bending equipment for reinforcing bars, which can solve the problem in related technologies where, during the bending process, the reinforcing bar deviates and comes into contact with other components of the device, causing it to deviate from the correct shaping and processing trajectory and strike the operator's body.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A safety range warning device for a CNC rebar bending machine includes multiple support columns. A bending platform is fixedly connected to the top of each support column. Display boards are fixedly connected to the sides of each support column. A fixing plate is fixedly connected to the inner wall of the bending platform. A rotating column is rotatably connected to the side of the fixing plate. The rotating column is driven by a motor, which is fixedly connected to the side of the fixing plate. A rotating disk is fixedly connected to the circumference of the rotating column. Bending clamps are fixedly connected to the inner wall of the rotating disk. Two fixing clamps are fixedly connected to the side of the bending platform. A protective device is provided on the circumference of the rotating column. The protective device includes an L-shaped rotating plate. The top of the L-shaped rotating plate is fixedly connected to the circumference of the rotating column. A baffle is fixedly connected to the side of the L-shaped rotating plate. A slot for the L-shaped rotating plate to rotate is provided on the side of the bending platform. A sensor, a buzzer, and a laser beam are fixedly connected to the top of the bending platform. A gap is left between the L-shaped rotating plate and the bending platform. The baffle is in contact with the bending platform.

[0008] The rotating column is equipped with an anti-fall device on its circumferential surface. The anti-fall device includes a first synchronous wheel, the inner wall of which is fixedly connected to the circumferential surface of the rotating column. A connecting plate is fixedly connected to the side of the bending platform. A second synchronous wheel is rotatably connected to the side of the connecting plate. A synchronous belt is rotatably connected to the inner wall of the first synchronous wheel. The end of the synchronous belt away from the first synchronous wheel is rotatably connected to the inner wall of the second synchronous wheel. A threaded rod is fixedly connected to the side of the second synchronous wheel. A limiting rod is fixedly connected to the side of the connecting plate. A stop is fixedly connected to the end of the limiting rod away from the connecting plate. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A moving plate is fixedly connected to the circumferential surface of the threaded sleeve. A limiting plate is fixedly connected to the side of the moving plate. The threaded rod contacts the stop, and the threaded sleeve contacts the limiting rod. A gap is left between the synchronous belt and the bending platform, and the moving plate contacts the bending platform.

[0009] The technical effects achieved by this utility model are as follows:

[0010] This invention utilizes a laser beam lamp to coordinate the use of sensors, a buzzer, and the laser beam lamp. When a straight steel bar bends upward, if the sensor in close contact with the device detects an obstruction directly above the steel bar, the buzzer will sound an alarm and emit a laser beam upward to alert personnel to leave the area where the steel bar is bent, thereby preventing them from being struck on the head or body by the steel bar.

[0011] This invention, through the inclusion of a protective device, coordinates the rotating column, rotating disc, bending clamp, L-shaped rotating plate, and baffle. The rotation of the rotating column drives the rotation of the L-shaped rotating plate, which in turn drives the rotation of the baffle. This prevents the reinforcing bars from shifting during bending, avoiding equipment malfunctions and additional burdens on the equipment. It ensures that the bending angle, radius, and shape of each reinforcing bar remain consistent, preventing errors or substandard products, improving the production pass rate, and reducing the incidence of scrap and rework.

[0012] This utility model, through the setting of an anti-fall device, enables the coordination of synchronous pulley one, synchronous pulley two, synchronous belt, threaded rod, threaded sleeve, moving plate, and limiting plate. The movement of the threaded sleeve drives the movement of the moving plate, and the movement of the moving plate drives the movement of the limiting plate, thereby preventing the rebar from falling during bending. It is adaptable to rebars of different diameters, materials, and types. The spacing of the plates is adjusted according to the specifications of the rebar to ensure that the rebar is always in the correct bending position, preventing injury to the operator in case of accidental rebar falling, and ensuring the safety of the operator.

Bending clamps 9 are fixedly connected to the inner wall of the rotating disk 8. Two fixing clamps 10 are fixedly connected to the side of the bending platform 2. A protective device 4 is provided on the circumferential surface of the moving column 7. The protective device 4 includes an L-shaped rotating plate 41.

A gap is left between the L-shaped rotating plate 41 and the bending platform 2. The baffle 42 is in contact with the bending platform 2.

[0023] According to the above structure, when the straight steel bar bends upward, if the sensor 11, which is in close contact with the equipment, detects an obstruction directly above the steel bar, the buzzer 12 will sound an alarm and emit a laser beam upward to prompt personnel to leave the bending area of ​​the steel bar, thereby avoiding being hit on the head or body by the steel bar. The motor corresponding to the rotating column 7 will be started. The rotation of the motor output shaft will drive the rotation of the rotating column 7, which in turn will drive the rotation of the rotating disk 8. The rotation of the rotating disk 8 will drive the rotation of the bending clamp 9, and the rotation of the rotating column 7 will drive the rotation of the L-shaped rotating plate 41. The rotation of the L-shaped rotating plate 41 will drive the rotation of the baffle 42, thereby preventing the steel bar from shifting during the bending process, avoiding equipment failure and additional burden on the equipment, ensuring that the bending angle, radius and shape of each steel bar are consistent, avoiding errors or unqualified products, improving the production qualification rate and reducing the occurrence of scrap and rework.

The moving plate 59 is in contact with the bending platform 2.

[0025] According to the above structure, the rotation of the rotating column 7 drives the rotation of the first synchronous pulley 51, which in turn drives the rotation of the synchronous belt 54. The rotation of the synchronous belt 54 drives the rotation of the second synchronous pulley 53, which in turn drives the rotation of the threaded rod 55. The rotation of the threaded rod 55 drives the movement of the threaded sleeve 58. The limiting rod 56 prevents the threaded sleeve 58 from rotating. The movement of the threaded sleeve 58 drives the movement of the moving plate 59, which in turn drives the movement of the limiting plate 510.
